ABSTRACT:
An adder comprising a tree-based carry structure, wherein the maximum fanout from any gate in the carry structure is three. When calculating optimized fanout, it is necessary to consider input capacitance to the following stage. In minimizing propagation delay, it is necessary to consider loading and the number of stages. It has been recognized that optimum fanout of e results in optimized propagation through the adder, thus fanout of three is the closest whole number. A cell has been designed which includes the necessary and sufficient circuitry for building multicell adders in a highly optimized structure. The cell provides individually accessible components and dedicated components for optimum layout in the end product.
